    Directory of Open Access Journals (Sweden)

    Imrich Ruisel

    2015-09-01

    Full Text Available The beginnings of modern Greek philosophy have already indicated that man is not a reliable information processor, because he is unable to completely encompass the real world at a cognitive level. Thus, already Plato distinguished between the knowledge of the real true belief (epistémé and opinion (doxa. F. Bacon assumed that human senses are not the measure of reality. Psychologists A. Tversky and D. Kahneman pointed out that people do not follow rational arguments and set rules in their judgments. Rather, they use heuristics, which are simplified judgment rules that enable quick judgments, often biased by individual’s subjective beliefs. These wrong conclusions induce false ideas or fallacies. There are deductive and inductive fallacies. We contemplate the ratio of cognitive fallacies in forming and existence of conspiracy theories. Deliberate use of fallacies and biases is characteristic of the use of conspiracy theories in propaganda. Wrong judgments are made due to wrong understanding of coincidental events, insufficient processing of the laws of statistical regression and the tendency to search for confirmation. Preferred are verbal techniques in the form of naive and ritualized terms and statements based on unidentifiable fallacies.

  3. Peniaze ako zdroj šťastia v našich životoch? (Is Money a Source of Happiness in our lives?

    Directory of Open Access Journals (Sweden)

    Otakar Horák

    2013-06-01

    Full Text Available This paper begins by referring to the research which distinguishes two different aspects of subjective well-being, namely 1. experiences of happiness – measured by frequency and intensity of joy, stress, anger, worry and sadness we experience at a certain moment and 2. life satisfaction. Survey shows that beyond an annual household income of $75 000 there is no increase in the experiences of happiness. The paper then refers to the psychological mechanisms and factors – namely hedonic adaptation, social comparison and stress as a result of a raise – that lower the capacity of money to buy us the experiences of happiness. Not only we get quickly used to the things we buy, money also puts us into stressful situations and makes us build barriers between people. The paper then specifies strategies of economic decision-making that contribute to the maximization of happiness, such as purchase of the experiences instead of the things, interrupted and postponed consumption, or prosocial spending. The research indicates that prosocial spending has higher causal impact on promoting happiness than personal spending. As a matter of fact, this phenomenon is not culturally limited to the West. Concluding assertion – expressed only in the form of hypothesis – says that prosocial spending which is a form of prosocial behavior strengthens – through production of happiness – mutual relations in the society (cooperation.

    2016-08-01

    The effects of dietary apricot kernel oil (AKO), which contains high levels of oleic and linoleic acids and lower levels of α-tocopherol, were evaluated in a rat model of cyclophosphamide-induced immunosuppression. Rats had intraperitoneal injection with cyclophosphamide to induce immunosuppression and were then infused with AKO or normal saline (NS) for 4 weeks. Enzyme-linked immunosorbent assays were used to detect antimicrobial factors in lymphocytes and anti-inflammatory factors in hepatocytes. Hematoxylin & eosin staining was conducted prior to histopathological analysis of the spleen, liver, and thymus. Significant differences were observed between the immune functions of the healthy control group, the normal saline group, and the AKO group. Compared to the normal saline-treated group, lymphocytes isolated from rats administered AKO showed significant improvement in immunoglobulin (Ig)A, IgM, IgG, interleukin (IL)-2, IL-12, and tumor necrosis factor-α (TNF-α) levels (p cyclophosphamide-associated organ degeneration. These results suggested that AKO may enhance the immune system in vivo. These effects may reflect the activities of intermediate oleic and linoleic acid metabolites, which play a vital role in the immune system, and the α-tocopherol in AKO may further enhance this phenomenon. Thus, the use of AKO as a nutritional supplement can be proposed to ameliorate chemotherapy-associated immunosuppression. PMID:27262314

    Full Text Available Abstract Background We have developed a culture system for the efficient and directed differentiation of human embryonic stem cells (HESCs to neural precursors and neurons. HESC were maintained by manual passaging and were differentiated to a morphologically distinct OCT-4+/SSEA-4- monolayer cell type prior to the derivation of embryoid bodies. Embryoid bodies were grown in suspension in serum free conditions, in the presence of 50% conditioned medium from the human hepatocarcinoma cell line HepG2 (MedII. Results A neural precursor population was observed within HESC derived serum free embryoid bodies cultured in MedII conditioned medium, around 7–10 days after derivation. The neural precursors were organized into rosettes comprised of a central cavity surrounded by ring of cells, 4 to 8 cells in width. The central cells within rosettes were proliferating, as indicated by the presence of condensed mitotic chromosomes and by phosphoHistone H3 immunostaining. When plated and maintained in adherent culture, the rosettes of neural precursors were surrounded by large interwoven networks of neurites. Immunostaining demonstrated the expression of nestin in rosettes and associated non-neuronal cell types, and a radial expression of Map-2 in rosettes. Differentiated neurons expressed the markers Map-2 and Neurofilament H, and a subpopulation of the neurons expressed tyrosine hydroxylase, a marker for dopaminergic neurons. Conclusion This novel directed differentiation approach led to the efficient derivation of neuronal cultures from HESCs, including the differentiation of tyrosine hydroxylase expressing neurons. HESC were morphologically differentiated to a monolayer OCT-4+ cell type, which was used to derive embryoid bodies directly into serum free conditions. Exposure to the MedII conditioned medium enhanced the derivation of neural precursors, the first example of the effect of this conditioned medium on HESC.

    Brown (BAT) and white (WAT) adipose tissues play distinct roles in maintaining whole-body energy homeostasis, and their dysfunction can contribute to non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes. The AMP-activated protein kinase (AMPK) is a cellular energy sensor, but its role in regulating BAT and WAT metabolism is unclear. We generated an inducible model for deletion of the two AMPK β subunits in adipocytes (iβ1β2AKO) and found that iβ1β2AKO mice were cold intolerant and resistant to β-adrenergic activation of BAT and beiging of WAT. BAT from iβ1β2AKO mice had impairments in mitochondrial structure, function, and markers of mitophagy. In response to a high-fat diet, iβ1β2AKO mice more rapidly developed liver steatosis as well as glucose and insulin intolerance. Thus, AMPK in adipocytes is vital for maintaining mitochondrial integrity, responding to pharmacological agents and thermal stress, and protecting against nutrient-overload-induced NAFLD and insulin resistance.

    Full Text Available The presence of accessory muscle bellies and tendons in the hand is of great interest to the hand surgeons. Awareness of the variations of the muscles will serve as useful guide for both in studies of human anatomy and in clinical practice today; this knowledge can be borne in mind while performing hand surgeries, tendon rerouting or transplants. These extra muscles often present as a ganglion, soft tissue tumor or mass in the hand, which could be quite misleading to the surgeon. With the purpose of preparation of the teaching and museum specimens, in two of the cadavers of elderly Jamaican African male and female, we observed accessory muscles on the dorsum of the hand. One was inserted to the index finger (extensor digitorum brevis manus and the other was arising deep to the extensor digitorum and inserted to the middle finger (extensor medii proprius.

  18. Disruption of cagA, the apoprotein gene of chromoprotein antibiotic C-1027, eliminates holo-antibiotic production, but not the cytotoxic chromophore.

    Science.gov (United States)

    Cui, Zhihui; Wang, Lifei; Wang, Songmei; Li, Guangwei; Hong, Bin

    2009-11-01

    C-1027 is a chromoprotein of the nine-membered enediyne antitumour antibiotic family, comprising apoprotein to stabilize and transport the enediyne chromophore. The disruption of apoprotein gene cagA within the C-1027 biosynthetic gene cluster abolished C-1027 holo-antibiotic production detected by an antibacterial assay, as well as the expression of the apoprotein and C-1027 chromophore extracted following protein precipitation of the culture supernatant. Complementation of the cagA-disrupted mutant AKO with the intact cagA gene restored C-1027 production, suggesting that cagA is indispensable for holo-antibiotic production. Overexpression of cagA in the wild-type strain resulted in a significant increase in C-1027 production as expected. Surprisingly, electrospray ionization (ESI)-MS and ESI-MS/MS analyses suggested that the AKO mutant still produced the C-1027 enediyne chromophore [m/z=844 (M+H)(+)] and its aromatized product [m/z=846 (M+H)(+)]. Consistent with this, the results from gene expression analysis using real-time reverse transcriptase-PCR showed that transcripts of the positive regulator sgcR3 and the structural genes sgcA1, sgcC4, sgcD6 and sgcE were readily detected in the AKO mutant as well as in the wild-type and the complementation strain. These results provided, for the first time, evidence suggesting that the apoprotein of C-1027 is not essential in the self-resistance mechanism for the enediyne chromophore. PMID:19845765

    Full Text Available The ‘Mierzwice’ nature reserve (forest district 206b, c and d of the Sarnaki Forest Inspectorate, situated in the area of the Podlaski Przełom Bug Landscape Park, is one of the most valuable natural assets of the central Bug river valley. The 12.98 ha reserve was established in 2010 to aid protection of the stand of xerothermic vegetation and its surrounding deciduous forest. In total, eight plant associations were identified within the reserve: Geranio-Peucedanetum cervariae, Geranio-Anemonetum sylvestris, Geranio-Trifolietum alpestris, Trifolio medii-Agrimonietum, Rubo fruticosi-Prunetum, Rhamno-Cornetum sanguinei, Potentillo albae-Quercetum and Tilio cordatae-Carpinetum betuli. Furthermore, 23 protected and 31 endangered species were found in the reserve including the following examples: Cephalanthera rubra, Thesium ebracteatum, Cypripedium calceolus, Gentiana cruciata, Anemone sylvestris, Cimicifuga europaea, Viola rupestris, Crepis praemorsa, Asperula tinctoria, Stachys recta, Laserpitium latifolium. Over the last few years, a regression of the species diagnostic number for thermophilous oak forests and xerothermic grasslands has been observed as a result of succession and expansion of Calamagrostis epigejos. Active protection of xerothermic vegetation such as uprooting of trees and bushes, regular grazing or mowing has been suggested in order to prevent the expansion of Calamagrostis epigejos.

  5. Methionine sulfoxide reductase A affects β-amyloid solubility and mitochondrial function in a mouse model of Alzheimer's disease.

    2016-03-15

    Accumulation of oxidized proteins, and especially β-amyloid (Aβ), is thought to be one of the common causes of Alzheimer's disease (AD). The current studies determine the effect of an in vivo methionine sulfoxidation of Aβ through ablation of the methionine sulfoxide reductase A (MsrA) in a mouse model of AD, a mouse that overexpresses amyloid precursor protein (APP) and Aβ in neurons. Lack of MsrA fosters the formation of methionine sulfoxide in proteins, and thus its ablation in the AD-mouse model will increase the formation of methionine sulfoxide in Aβ. Indeed, the novel MsrA-deficient APP mice (APP(+)/MsrAKO) exhibited higher levels of soluble Aβ in brain compared with APP(+) mice. Furthermore, mitochondrial respiration and the activity of cytochrome c oxidase were compromised in the APP(+)/MsrAKO compared with control mice. These results suggest that lower MsrA activity modifies Aβ solubility properties and causes mitochondrial dysfunction, and augmenting its activity may be beneficial in delaying AD progression.

    Alteration of the acetylation status of chromatin and other non-histone proteins by HDAC inhibitors has evolved as an excellent epigenetic strategy in treatment of cancers. The present study was sought to identify compounds with positive pharmacological profiles targeting HDAC1. Analogues of Vorinostat synthesized by Cai et al, 2015 formed the test compounds for the present pharmacological evaluation. Hydroxamte analogue 6H showed superior pharmacological profile in comparison to all the compounds in the analogue dataset owing to its better electrostatic interactions and hydrogen bonding patterns. In order to identify compounds with even better high affinity and pharmacological profile than 6H and Vorinostat, virtual screening was performed. A total of 83 compounds similar to Vorinostat and 154 compounds akin to analogue 6H were retrieved. SCHEMBL15675695 (PubCid: 15739209) and AKOS019005527 (PubCid: 80442147) similar to Vorinostat and 6H, were the best docked compounds among the virtually screened compounds. However, in spite of having good affinity, none of the virtually screened compounds had better affinity than that of 6H. In addition SCHEMBL15675695 was predicted to be a carcinogen while AKOS019005527 is Ames toxic. From, our extensive analysis involving binding affinity analysis, ADMET properties predictions and pharmacophoric mappings, we report Vorinostat hydroxamate analogue 6H to be a potential candidate for HDAC inhibition in treatment of cancers through an epigenetic strategy.

  12. Hlf is a genetic modifier of epilepsy caused by voltage-gated sodium channel mutations.

    Science.gov (United States)

    Hawkins, Nicole A; Kearney, Jennifer A

    2016-01-01

    Mutations in voltage-gated sodium channel genes cause several types of human epilepsies. Often, individuals with the same sodium channel mutation exhibit diverse phenotypes. This suggests that factors beyond the primary mutation influence disease severity, including genetic modifiers. Mouse epilepsy models with voltage-gated sodium channel mutations exhibit strain-dependent phenotype variability, supporting a contribution of genetic modifiers in epilepsy. The Scn2a(Q54) (Q54) mouse model has a strain-dependent epilepsy phenotype. Q54 mice on the C57BL/6J (B6) strain exhibit delayed seizure onset and improved survival compared to [B6xSJL/J]F1.Q54 mice. We previously mapped two dominant modifier loci that influence Q54 seizure susceptibility and identified Hlf (hepatic leukemia factor) as a candidate modifier gene at one locus. Hlf and other PAR bZIP transcription factors had previously been associated with spontaneous seizures in mice thought to be caused by down-regulation of the pyridoxine pathway. An Hlf targeted knockout mouse model was used to evaluate the effect of Hlf deletion on Q54 phenotype severity. Hlf(KO/KO);Q54 double mutant mice exhibited elevated frequency and reduced survival compared to Q54 controls. To determine if direct modulation of the pyridoxine pathway could alter the Q54 phenotype, mice were maintained on a pyridoxine-deficient diet for 6 weeks. Dietary pyridoxine deficiency resulted in elevated seizure frequency and decreased survival in Q54 mice compared to control diet. To determine if Hlf could modify other epilepsies, Hlf(KO/+) mice were crossed with the Scn1a(KO/+) Dravet syndrome mouse model to examine the effect on premature lethality. Hlf(KO/+);Scn1a(KO/+) offspring exhibited decreased survival compared to Scn1a(KO/+) controls. Together these results demonstrate that Hlf is a genetic modifier of epilepsy caused by voltage-gated sodium channel mutations and that modulation of the pyridoxine pathway can also influence phenotype

  13. Determination of gamma radiation shielding characteristics of some tropical woods

    International Nuclear Information System (INIS)

    This study compares the shielding characteristics of twenty-two tropical woods by using gamma scintillation detection method. Woods sourced are Anogeisus Leiocarpus(Ayin), Nesogordonia Papverifera(Oro), Entandrophragma Microphyllum(Anunje), Brachystagia Eurycoma(Ako), Cassia Alata(Asunrun), Afzelia Africana(Apa-Igbo), Khaya Grandifoliala(Gedu), Piptadenistrum Africana(Agbonyin), Nanclea Diderrehii(Opepe), Khaya Ivorensis(Oganwo), Chlorophora Excelsa(Iroko), Masonia altissima(Odogi), Entandrophragma Angolense(Ijebo), Altium Sativum(Ayo), Albizia Zygia(Ayunre), Terminalia Superba(Afara), Cordia Millenii(Omo), Melania(Melania), Pycnanthus Angolensis(Akomu), Triplochitons Scleroxylon(Arere), Pine(Pine), Ceiba Pentradra(Araba). The intensities of the emergent radiation were measured, when each of these woods were placed between a scintillation detector and a standard radioactive source. Analysis of result obtained shows an appreciable evidence of radiation attenuation due to the changes in the chemical composition of the woods and the dependence of the attenuation coefficient on energy and densities of these woods. The descending order of attenuation coefficient determined are; Ayin, Oro, Anuje, Ako, Asunrun, Apa-igbo Gedu, Agbonyin, Opepe Oganwo, Iroko Odogi , Ayo, Ayunre, Afara, Omo, Melania, Akomu, Arere, Pine, Araba.

    A total of 83 male Japanese quails of the following age groups were used for this study: 11, 18, 25, 32, 35, 37, 39, 41, 43 days, and 7, 9, 17 weeks after hatching. Neoprene-Latex, Tensol-Cement, and the china ink were injected via the aortic arch. In most of male Japanese quails, the testes are supplied by the A. testicularis originated from the Aorta descendens through a common trunk with the A. renalis cranialis. But in only 3 quails had this artery originated directly from the Aorta descendens on either side. In 9 quails had the A. testicularis accessoria originating independently from the Aorta descendens and running cranially or caudally in short distance to the normal A. testicularis. The arteries for the Ductus deferens were divided into 3 categories. The Rami ureterodeferentiales craniales were spread out from A. testicularis or Rami epididymales. The Rami ureterodeferentiales medii came from the A. renalis media and the A. renalis caudalis. The Rami ureterodeferentiales caudales originated from the A. caudae lateralis and A. pudenda. The Receptaculum ductus deferentis, the Corpus vasculare paracloacalis and the Phallus nonprotrudens in the Cloaca were supplied from the thick Ramus cloacalis of the A. pudenda. The Ramus bursalis of this artery supplied the Glandula proctodaealis and the Bursa cloacalis, and was also thick. The arteries to the genital organs were observed in the 11 day old male quail. The A. pudenda began developing at about 30 days after hatching when the quail's body matured. While the A. testicularis began developing at about 40 days after hatching when the male Japanese quail was full of the spermatogenic activity. PMID:1497141

  16. Slow neutrons and secondary gamma ray distributions in concrete shields followed by reflecting layers

    International Nuclear Information System (INIS)

    Slow neutrons and secondary gamma ray distributions in concrete shields with and without a reflecting layer behind layer behind the concrete shield have been investigated first in case of using a bare reactor beam and then on using a B-4 C filtered beam. The total and capture secondary gamma ray coefficient (B gamma and B gammaC), the ratio of the reflected thermal neutron (gamma) the ratio of the secondary gamma rays caused by reflected neutrons to those caused transmitted neutrons (ThI gamma/FI gamma) and the effect of inserting a blocking layer (a B-4 C layer) between the concrete shield and the reflector on the suppression of the produced secondary gamma rays have been investigated. It was found that the presence of the reflector layer behind the concrete shield reflects some thermal neutrons back to the concrete shields and so it increases the number of thermal neutrons at the interface between the concrete shield and the reflector. Also the capture secondary gamma rays was increased at the interface between the two medii due to the capture of the reflected thermal neutrons in the concrete shields. It was shown that B-gamma is higher than and that Bgamma B gammaC and I gammaTh/ I gammaif for the different concrete types is higher in case of using the graphite reflector than that in using either water or paraffin reflectors. Putting a blocking layer (B4C layer) between the concrete shield and the reflector decreases the produced secondary gamma rays due to the absorption of the reflected thermal neutrons. 17 figs

Britanski ekonomist John Maynard Keynes još za Velike Depresije 1929. uočava da ne postoji jamstvo za takvo što jer tržište nije zbroj racionalnih individua.

Použili sme model ELBA+, pomocou ktorého sme snažili zhodnotiť ohrozenosť horského prostredia v okolí starej banskej osady Magurka (1 036 m n. m., ktorá leží v závere Ľupčianskej doline pod hlavným hrebeňom Nízkych Tatier. Do histórie sa zapísala hlavne lavína v doline Ďurková zo 14. marca 1970, ktorá dodnes patrí medzi najväčšie lavíny zaznamenané na Slovensku. S použitím archívnych údajov Strediska lavínovej prevencie v Jasnej sme sa pokúsili o jej čo najvernejšiu rekonštrukciu. Následne sme sa pokúsili o simuláciu lavíny v doline Viedenka pri použití rovnakej výšky snehu v odtrhovom pásme ako sa predpokladá pri lavíne v roku 1970. Keďže časť osady Magurka je situovaných pri ústí tejto doliny, ktorá má priamejší aj kratší priebeh ako dolina Ďurková, skúmali sme možnosť jej zásahu lavínou.

    Full Text Available The aim of this study was to evaluate the influence of floor quality on the behaviour and cleanliness of the diary cow‘s body. The analysis results show that cows housed in the section with the separated manure solids spent more time lying (41.47% and also laid less in the corridor manure (0.91% than the cows in the section with separated manure solids and the rubber mats where they were laying generally less (35.71%, they spent more time lying in the corridor manure (1.55% and in terms of preference of lying area the cows clearly preferred the separated manure solids (25.8%. Based on observations we can say that cows housed in sections of slurry solid phase were cleaner (average 6.13 points than cows in the section with the rubber and a separated manure (averagely 7.28 points. Nowadays the free housing systems with different types of litter and boxes are frequently used, while the proper littering influences the lying preferences of an animal. In practice, for the dairy cows the deepened lying boxes littered with natural materials such as sawdust, shavings, straw, dried manure and sand boxes or elevated boxes covered with a synthetic material, mattresses or mats are used.Cieľom práce bolo zhodnotiť vplyv kvality podlahy na správanie a čistotu povrchu tela dojníc. Z analýzy výsledkov vyplýva, že dojnice ustajnené v sekcii so separovaným kalom hnojovice venovali ležaniu väčšiu časť (41,47% a ležali aj menej v hnojnej chodbe (0,91% ako dojnice v sekcii so separovaným kalom hnojovice aj gumenými matracmi, kde dojnice celkovo menej ležali (35,71%, viac času ležali v hnojnej chodbe (1,55% a z hľadiska uprednostňovania ležoviska ležali jednoznačne viac na separovanom kale hnojovice (25,8%. Na základe pozorovaní možno povedať, že dojnice ustajnené v sekciách so separovaným kalom hnojovice boli čistejšie (priemerne 6,13 bodov ako dojnice v sekcii so separovaným kalom hnojovice aj gumou (priemerne 7,28 bodov.

Na základe odberu vzorníkov celých stromov (všetky časti okrem jemných koreňov sme skonštruovali alometrické vzťahy pre stromové komponenty. Ako nezávislá premenná sa použila hrúbka na báze kmeňa (d0. Modely vyjadrili nielen biomasu konárov, kmeňa, hrubých koreňov a asimilačných orgánov, ale aj plochu asimilačných orgánov a špecifickú listovú plochu (specific leaf area; SLA. Zistili sme, že základné morfologické vlastnosti asimilačných orgánov varírovali pri obidvoch drevinách pozdĺž vertikálneho profilu koruny. V prípade smreka sa zistili odlišné hodnoty plochy ihlíc a SLA medzi jednotlivými ročníkmi ihlíc. Na úrovni stromu mali buky oveľa viac biomasy drevných častí ako smreky, opačná situácia bola pri asimilačných orgánoch. Preto hodnoty podielu medzi biomasou asimilačných orgánov a celkovou biomasou stromu, ako aj pomeru medzi plochou asimilačných orgánov a celkovou biomasou stromu boli výrazne vyššie pri smreku než buku. Na úrovni porastu mala smrečina vyššie hodnoty indexu listovej plochy, t. j. LAI (18,64 m2.m−2 v porovnaní s bučinou (12,77 m2.m−2. Kým biomasa asimilačných orgánov bola 4,6-krát väčšia v smrekovom než v bukovom poraste, biomasa drevných časti bola porovnateľná v obidvoch porastoch. Tieto kontrasty naznačujú výrazne odlišnú rastovú stratégiu, resp. alokáciu biomasy medzi bučinami a smrečinami v mladých štádiách

    Full Text Available Instrumentalne metode analize nezamjenjive su u znanstvenim istraživanjima, a sve više i u praksi gdje se zahtijeva što brže dobivanje rezultata, kao i što veća točnost. U metalurškoj praksi već se dulji niz godina primjenjuju spektrometrijske metode analize i to najčešće optička emisijska spektrometrija s izravnim očitanjem. Međutim koncentracija pojedinih legirnih elemenata u suvremenim metalnim materijalima vrlo je niska, često niža od granice detekcije optičkih emisijskih spektrometara s izravnim očitanjem. U ovom radu određivana je koncentracija bora u nodularnom lijevu primjenom optičke emisijske spektrometrije s izravnim očitanjem (OES, optičke emisijske spektrometrije s induktivno spregnutom plazmom (ICP-OES te atomske apsorpcijske spektrometrije s grafitnom tehnikom (AAS-GF. Dobiveni rezultati pokazali su da se optička emisijska spektrometrija s izravnim očitanjem i optička emisijska spektrometrija s induktivno spregnutom plazmom mogu primijeniti za određivanje bora u ispitivanim uzorcima (tablica 1. Ako se zahtijeva vrlo točna analiza, a posebno ako se radi o vrlo niskim koncentracijama, optička emisijska spektrometrija s induktivno spregnutom plazmom pogodnija je metoda, uz uvjet da su uzorci pravilno pripremljeni. Atomska apsorpcijska spektrometrija s grafitnom tehnikom nije pogodna za određivanje bora u uzorcima ovog tipa. Tijekom provođenja analize dodatna pažnja usmjerena je na eliminaciju negativnog utjecaja grafitne kivete na rezultat analize. Osim toga, u radu je praćen utjecaj načina otapanja uzoraka na rezultate analize bora spomenutim metodama. Rezultati su pokazali da pažljiva priprema uzoraka u zatvorenom sustavu pridonosi točnijem rezultatu analize.

Pri vykonávaní operácií môže CP prechádzať rôznymi stavmi, v dôsledku čoho táto jednotka predstavuje dynamický prúdový systém. Prechod a poradie prechodu medzi jednotlivými stavmi CP je podmienený typom spracovaného operátora pri interpretovaní prúdu operandov. Z možných typov operátorov, článok uvádza mikroprogramové riadenie pre jednovstupové operátory.

Posebno to važi za neplaćanje obveza u poduzetništvu. Poduzetništvo je po svojoj osnovi amoralno - što znači da ga nije moguće ocjenjivati pozitivnim ili negativnim moralnim predznakom ako se poštuju pravila poduzetništva. Tako npr. stečaj gospodarskog subjekta nije u osnovi nemoralan jer je to nužna pojava u kapitalizmu. U prosjeku je potrebno da oko 300 sudionika u poduzetništvu na njih 10 000 mora u stečaj jer inače kapitalistički sustav ne može djelovati i ne može biti efikasan. U socijalizmu nismo imali stečajeva i zato poduzetništvo nije moglo biti konkurentno s partnerima u kapitalističkim sustavima.

    2016-04-01

    Nature-based solutions for the management of urban stormwater have been growing in popularity, but there is a lack of empirical performance data for field-scale installations, especially in a UK context. To address this deficiency, a novel retrofit street tree demonstration project was commissioned in the City of Salford, near Manchester (UK). Three fifteen year-old London Plane trees were planted within a large roadside tree trench on an urban residential street. The DeepRoot Silvia Cell modular suspended pavement system was used to maximise soil volume, avoid compaction and support large tree growth. Road runoff is directed to the tree trench via AKO Slot Kerbs. Water is then distributed evenly throughout the whole system via a perforated pipe. Excess water is conveyed out of the system via an underdrain, which is subsequently connected to the sewer network. The tree trench is lined with an impermeable membrane. Access chambers are positioned on the inflow and outflow of the tree trench to facilitate hydrological and water quality monitoring. Installation was completed in autumn 2015 and monitoring will be conducted over a three year period. This paper will provide an overview of the installation process and present initial results on the pollutant removal performance and hydrological functioning of the system.

    Inhibition of EGFR-EGF interactions forms an important therapeutic rationale in treatment of non-small cell lung carcinoma. Established inhibitors have been successful in reducing proliferative processes observed in NSCLC, however patients suffer serious side effects. Considering the narrow therapeutic window of present EGFR inhibitors, the present study centred on identifying high efficacy EGFR inhibitors through structure based virtual screening strategies. Established inhibitors - Afatinib, Dacomitinib, Erlotinib, Lapatinib, Rociletinib formed parent compounds to retrieve similar compounds by linear fingerprint based tanimoto search with a threshold of 90%. The compounds (parents and respective similars) were docked at the EGF binding cleft of EGFR. Patch dock supervised protein-protein interactions were established between EGF and ligand (query and similar) bound and free states of EGFR. Compounds ADS103317, AKOS024836912, AGN-PC-0MXVWT, GNF-Pf-3539, SCHEMBL15205939 were retrieved respectively similar to Afatinib, Dacomitinib, Erlotinib, Lapatinib, Rociletinib. Compound- AGN-PC-0MXVWT akin to Erlotinib showed highest affinity against EGFR amongst all the compounds (parent and similar) assessed in the study. Further, AGN-PC-0MXVWT brought about significant blocking of EGFR-EGF interactions in addition showed appreciable ADMET properties and pharmacophoric features. In the study, we report AGN-PC-0MXVWT to be an efficient and high efficacy inhibitor of EGFR-EGF interactions identified through computational approaches.

Sabendo-se da importância dos receptores α2A/α2C-adrenérgicos na modulação da atividade nervosa e frequência cardíaca (FC, o presente trabalho utiliza um modelo genético de cardiomiopatia induzida por excesso de catecolaminas circulantes baseado na inativação gênica dos receptores α2A/α2C-adrenérgicos em camundongos (α2A/α2CKO para verificar a resposta da FC ao exercício físico (EF, assim como o controle simpatovagal da FC ao EF. Testou-se a hipótese de que haveria resposta taquicárdica exacerbada durante o EF nos camundongos α2A/α2CKO mesmo quando a função cardíaca ainda estivesse preservada em repouso, sendo o receptor α2A-adrenérgico o principal responsável por essa resposta.

Outros dois grupos de camundongos, CO e α2A/α2CKO, foram submetidos ao bloqueio farmacológico dos receptores muscarínicos e β-adrenérgicos e ao EF progressivo para se avaliar a contribuição simpatovagal para a taquicardia de EF. Observou-se intolerância ao esforço físico (1.220 ± 18 e 1.460 ± 34 vs. 2.630 ± 42m, respectivamente e maior taquicardia ao EF (765 ± 16 e 792 ± 13 vs. 603 ± 18bpm, respectivamente nos camundongos α2AKO e α2A/α2CKO vs. CO. Além disso, o balanço autonômico estava alterado nos camundongos α2A/α2CKO pela hiperatividade simpática e menor efeito vagal cardíaco. Esses resultados demonstram a importância dos receptores α2A/α2C-adrenérgicos no controle autonômico não só no repouso, mas também durante o EF, sendo o receptor α2A-adrenérgico o responsável pela hiperatividade simp

Využili sa údaje Národnej inventarizácie a monitoringu lesov SR (260 plôch a taktiež údaje z predchádzajúcich výskumných projektov (48 plôch tak aby reprezentovali čo najširšie rozpätie ekologických podmienok, v ktorých smrek v súčasnosti rastie. Výsledky ukázali, že najvýznamnejšími ekologickými faktormi boli: nadmorská výška a bonita stanovišťa. Taktiež niektoré porastové charakteristiky sa významne podieľali na variabilite kvocientu: podiel koruny z výšky stromu, hustota porastu a stredná porastová výška reprezentujúca rastovú fázu porastu. Výsledky ďalej preukázali, že ekologické podmienky sú významnejšie ako porastové charakteristiky, a preto tieto treba brať do úvahy pri rozhodovacom procese. To znamená, že ak sa porast nachádza na pre smrek veľmi bonitnom stanovišti, sú potrebné silnejšie prebierky od mladých rastových fáz, aby sa ovplyvňovaním hrúbkového prírastku vyrovnal vplyv rýchleho výškového rastu. Zároveň je dôležitá rozdielna intenzita výškového a hrúbkového rastu počas vývoja porastu

    Full Text Available Medzi základné práva a slobody, upravené v druhej hlave Ústavy Slovenskej republiky patrí aj právo na ochranu zdravia, bezplatnú zdravotnú starostlivosť na základe zdravotného poistenia, právo na zdravotnícke pomôcky za zákonom stanovených podmienok. Tieto práva sú garantované v ustanovení Čl. 40 Ústavy Slovenskej republiky v rámci ekonomických, sociálnych a kultúrnych práv a vzťahujú sa na každú fyzickú osobu, t. j. na človeka. Keďže sú tieto práva považované za ľudské práva v zmysle medzinárodného práva, sú garantované aj v mnohostranných medzinárodných zmluvách, ktorých signatárom je aj Slovenská republika, ako napríklad Medzinárodný pakt o hospodárskych, sociálnych a kultúrnych právach. Právna úprava prevádzkovania lekární v Slovenskej republike zahŕňa široké spektrum otázok a je pomerne rozsiahla. Snahou zákonodarcu bolo nastaviť také pravidlá, ktoré by stransparentnili a zjednodušili právne prostredie v tomto sektore. V niektorých oblastiach sú pravidlá dané legislatívou Európskej únie a slovenský právny poriadok ich iba prevzal. Najdôležitejším prvokom v tejto sfére, ktorý nie je priamo upravovaný legislatívou EÚ, je poskytovanie lekárenskej starostlivosti a využívanie systému verejného zdravotného poistenia v tejto oblasti. Hlavným cieľom príspevku je poukázať na vybrané problémy, ktoré sa spájajú s postavením prevádzkovateľa lekárne a jeho povinnosťami, ktoré mu vyplývajú zo zákona o liekoch a s ktorými sa musí ako prevádzkovateľ lekárne vysporiadať. Táto oblasť podnikania je pomerne prísne regulovaná a preto je potrebné byť oboznámený s príslušnými právnymi predpismi. Príspevok z právno-teoretického hľadiska rieši viaceré otázky upravené v zákone o liekoch, či vyhláške o správnej lekárenskej praxi.

    Full Text Available Pjesništvo Susanne Jorn intimno je s mnogo kratkih pjesama koje često izražavaju osjećaje, atmosferu i dojmove. Tu su osobna viđenja prirode i ljudi, doživljena, mogli bismo reći, na slikarski način. Boje su gotovo redoviti sastavni dio tih doživljaja i kao na slikama, stvaraju dramatičnu ili smirenu atmosferu. One su izraz prirode koja okružuje pjesnikinju, ali su i izraz osjećaja i duševnih stanja. To se jasno pokazuje u zbirci Ne sada već sad, čiji je okvir paleta plavih boja. Druga scena njezine poezije sličice su iz japanskog života i japanske umjetnosti i pjesništva, koje mnogo puta prenosi u svoju dansku okolinu. U zbirci Ne sada već sad mnoge su pjesme prizori iz Danske ili Tokija, ali i drugih krajeva svijeta gdje je boravila. Ipak, njezino je pjesništvo prije svega vezano uz nordijsko nebo, zemlju i kulturu te sjećanja na oca (poznatog danskog likovnog umjetnika Asgera Jorna, koji je u svojim djelima spajao različite vrste umjetnosti. Asger Jorn bio je član poznate transnacionalne udruge CoBrA, koja je djelovala početkom 1950-ih godina. U mnoge se pjesme određenih osjećaja i ozračja skladno uklapaju i japanski i danski krajolici te japanski i, ako tako možemo reći, nordijski pjesnički izraz. Unatoč vrlo intimnoj poeziji, kao i većina skandinavskih pjesnika i pjesnikinja, Susanne Jorn osjetljiva je na sudbu današnjeg čovjeka bilo gdje u svijetu i ona nalazi značajno mjesto u njezinu pjesništvu.

    Full Text Available Europska unija nastoji poboljšati europsko energetsko tržište na način da bude bolje koordinirano, jer u ujedinjenoj Europi nije više moguće djelovati izdvojeno. Proizvodnja energije iz obnovljivih izvora velikih razmjera zahtijeva međusobno povezano europsko energetsko tržište, ako se žele postići ciljevi utvrđeni programom „Energija i klima“ usvojenim 2009. Cilj je ovog rada utvrditi na koji način utječu pravila europskog prava na pravno normiranje u energetskim pitanjima i borbi protiv globalnog zatopljenja. Razvoj energija koje ne emitiraju ugljični dioksid u skladu je s ciljevima koje postavlja Europska unija, koji se u tom području oslanja na regije, a ne više na same države koje nisu uvijek u mogućnosti provesti definirane ambiciozne ciljeve. Energija nastavlja ovisiti u većini slučajeva o snazi država i europska nadležnost je ograničena. Europska unija sudjeluje uglavnom u koordiniranju i podržavanju nacionalnih politika, u okviru odredaba koje se odnose na transeuropske mreže i u okviru politike zaštite okoliša.

  1. Pleiotropic effects of methionine adenosyltransferases deregulation as determinants of liver cancer progression and prognosis.

    Science.gov (United States)

    Frau, Maddalena; Feo, Francesco; Pascale, Rosa M

    2013-10-01

    Downregulation of liver-specific MAT1A gene, encoding S-adenosylmethionine (SAM) synthesizing isozymes MATI/III, and upregulation of widely expressed MAT2A, encoding MATII isozyme, known as MAT1A:MAT2A switch, occurs in hepatocellular carcinoma (HCC). Being inhibited by its reaction product, MATII isoform upregulation cannot compensate for MATI/III decrease. Therefore, MAT1A:MAT2A switch contributes to decrease in SAM level in rodent and human hepatocarcinogenesis. SAM administration to carcinogen-treated rats prevents hepatocarcinogenesis, whereas MAT1A-KO mice, characterized by chronic SAM deficiency, exhibit macrovesicular steatosis, mononuclear cell infiltration in periportal areas, and HCC development. This review focuses upon the pleiotropic changes, induced by MAT1A/MAT2A switch, associated with HCC development. Epigenetic control of MATs expression occurs at transcriptional and post-transcriptional levels. In HCC cells, MAT1A/MAT2A switch is associated with global DNA hypomethylation, decrease in DNA repair, genomic instability, and signaling deregulation including c-MYC overexpression, rise in polyamine synthesis, upregulation of RAS/ERK, IKK/NF-kB, PI3K/AKT, and LKB1/AMPK axis. Furthermore, decrease in MAT1A expression and SAM levels results in increased HCC cell proliferation, cell survival, and microvascularization. All of these changes are reversed by SAM treatment in vivo or forced MAT1A overexpression or MAT2A inhibition in cultured HCC cells. In human HCC, MAT1A:MAT2A and MATI/III:MATII ratios correlate negatively with cell proliferation and genomic instability, and positively with apoptosis and global DNA methylation. This suggests that SAM decrease and MATs deregulation represent potential therapeutic targets for HCC. Finally, MATI/III:MATII ratio strongly predicts patients' survival length suggesting that MAT1A:MAT2A expression ratio is a putative prognostic marker for human HCC.

    Full Text Available Dosta je krivice koja se deli u ovoj krizi. Videli smo ulogu regulatornih tela i zakonodavaca, FED-a i finansijera, svih njih koji su bili u igri. Svako od njih je govorio o svom interesu zauzimajući stav da su bili u pravu za ono što su radili a veoma često zasnivajući svoje stavove na ekonomskoj analizi. Kada počne raslojavanje pitanja šta je pošlo naopako ne može se izostaviti fokus sa ekonomske profesije. Naravno, nisu se svi ekonomisti pridružili slavi slobodnog ekonomskog tržišta i nisu svi bili sledbenici Miltona Fridmana. Iznenađujuće je što je ipak, veliki deo bio naklonjen tom pravcu. Ne samo da je njihov savet bio pogrešan već su bile pogrešne i osnovne pretpostavke i predviđanja. Relativno mali broj njih je mogao da vidi nadolazeću katastrofu. Nije bilo slučajno da su oni, koji su se zalagali za pravila koja su dovela do nesreće, bili toliko zaslepljeni svojom verom u slobodno tržište te nisu mogli da vide probleme koji nastaju. Ekonomija se promenila više nego što su to ekonomisti želeli da veruju, do te mere da je od naučne discipline postala navijačica discipline slobodnog tržišta. Ako SAD želi da uspe u reformi privrede, moraće da počne sa reformom ekonomije.

    Hemorrhagic cystitis often arises after cyclophosphamide (CYP) administration. As yet, however, the mechanism involved in its pathogenesis is unknown. In this study, it was found that the Fc receptor γ chain (FcRγ)- caspase recruitment domain-containing protein 9 (CARD9)-dependent pathway rather than the myeloid differentiation primary response gene 88 (MyD88)-dependent pathway is involved in the pathogenesis of acute CYP-induced cystitis in mice. Rapid and transient production of interleukin (IL)-6 and IL-1β was detected in the bladder at 4 hr, preceding IL-23 and IL-17A production and an influx of neutrophils, which reached a peak at 24 hr after injection. As assessed by weight, edema and neutrophil infiltration, cystitis was significantly attenuated in CARD9 knockout (KO) and FcRγKO mice, this attenuation being accompanied by impaired production of IL-1β, IL-6, IL-23 and IL-17A. The major source of IL-17A is the vesical γδ T cell population: IL-17AKO, CδKO and Tyk2KO mice showed little IL-17A production and reduced neutrophil infiltration in the bladder after CYP injection. These results suggest that FcRγ-CARD9-dependent production of proinflammatory cytokines such as IL-1β, IL-6, and IL-23 and the subsequent activation of IL-17A-producing γδ T cells are at least partly involved in the pathogenesis of acute CYP-induced cystitis in mice.

The intention-to-treat analysis showed effectiveness rates of 94.5% and 93.5% for ASAQ and AL, respectively on day 28. After adjustment for PCR results, these rates were 96.1% and 96.8%, respectively. On day 28, the per-protocol analysis showed effectiveness rates of 98.4% and 96.6% for ASAQ and AL, respectively. After adjustment by PCR for reinfection, these rates were 100% for each drug, and both regimens were well tolerated. Conclusion: ASAQ and AL remain efficacious treatments of uncomplicated falciparum malaria in Ivorian children 5 years after adoption. The efficacy of ASAQ and AL in Côte d'Ivoire requires, therefore, continuous

    Pyrenophora teres f. sp. teres is the cause of net form of net blotch (NFNB), an economically important foliar disease in barley (Hordeum vulgare). Net and spot forms of net blotch are widely controlled using site-specific systemic fungicides. Although resistance to succinate dehydrogenase inhibitors and quinone outside inhibitors has been addressed before in net blotches, mechanisms controlling demethylation inhibitor resistance have not yet been reported at the molecular level. Here we report the isolation of strains of NFNB in Australia since 2013 resistant to a range of demethylase inhibitor fungicides. Cyp51A:KO103-A1, an allele with the mutation F489L, corresponding to the archetype F495I in Aspergillus fumigatus, was only present in resistant strains and was correlated with resistance factors to various demethylase inhibitors ranging from 1.1 for epoxiconazole to 31.7 for prochloraz. Structural in silico modeling of the sensitive and resistant CYP51A proteins docked with different demethylase inhibitor fungicides showed how the interaction of F489L within the heme cavity produced a localized constriction of the region adjacent to the docking site that is predicted to result in lower binding affinities. Resistant strains also displayed enhanced induced expression of the two Cyp51A paralogs and of Cyp51B genes. While Cyp51B was found to be constitutively expressed in the absence of fungicide, Cyp51A was only detected at extremely low levels. Under fungicide induction, expression of Cyp51B, Cyp51A2, and Cyp51A1 was shown to be 1.6-, 3,- and 5.3-fold higher, respectively in the resistant isolate compared to the wild type. These increased levels of expression were not supported by changes in the promoters of any of the three genes. The implications of these findings on demethylase inhibitor activity will require current net blotch management strategies to be reconsidered in order to avoid the development of further resistance and preserve the lifespan of

V tejto štúdii prezentujeme faktory mortality a prežívanie mladých a imaturných A. heliaca z Bulharska na základe štúdia satelitnou telemetriou. Celkom bolo v hniezdach v Bulharsku vysielackami GPS / Argos oznacených 20 mladých A. heliaca. Štrnást vtákov bolo sledovaných až do smrti vrátane nálezov kadáverov. Ide o prvé takéto štúdium prežívania mladých a imaturných jedincov A. heliaca. Prežívanie má hodnotu 59.1 % v prvom kalendárnom roku, 83.3 % v druhom a 80,0 % v tretom kalendárnom roku. Hlavným faktorom mortality sledovaných jedincov z bulharskej populácie je smrt v dôsledku zásahu elektrickým prúdom, ktorý spôsobil 59,0 % prípadov mortality. Dalšie identifikované hrozby sú zástrely, otravy a kolízie. Väcšina prípadov mortality sledovaných orlov nastala v Bulharsku (50% a v Turecku (43%. Preto je Turecko klúcovou krajinou pre ochranu bulharskej populácie A. heliaca pocas jeho disperzie. Orly z Bulharska sa rozptylujú aj dalej na juh, do Sudánu a do Saudskej Arábie. Preto je potrebné ochranárske úsilie s cielom zníženia mortality tak vo vnútri ako aj mimo Bulharska. Medzinárodná spolupráca a výmena skúseností by preto mala byt súcastou každej stratégie ochrany a plánov zameraných na ochranu orla královského.

    This paper summarizes a study performed by ten students at the Delft University of Technology on a lunar exploration vehicle suited for competing in the Google Lunar X Prize1. The design philosophy aimed at a quick and simple design process, to comply with the mission constraints. This is achieved by using conventional technology and performing the mission with two identical rovers, increasing reliability and simplicity of systems. Both rovers are however capable of operating independently. The required subsystems have been designed for survival and operation on the lunar surface for an estimated mission lifetime of five days. This preliminary study shows that it is possible for two nano-rovers to perform the basic exploration tasks. The mission has been devised such that after launch the rovers endure a 160 hour voyage to the Moon after which they will land on Sinus Medii with a dedicated lunar transfer/lander vehicle. The mission outline itself has the two nano-rovers travelling in the same direction, moving simultaneously. This mission characteristic allows a quick take-over of the required tasks by the second rover in case of one rover breakdown. The main structure of the rovers will consist of Aluminium 2219 T851, due to its good thermal properties and high hardness. Because of the small dimensions of the rovers, the vehicles will use rigid caterpillar tracks as locomotion system. The track systems are sealed from lunar dust using closed track to prevent interference with the mechanisms. This also prevents any damage to the electronics inside the tracks. For the movement speed a velocity of 0.055 m/s has been determined. This is about 90% of the maximum rover velocity, allowing direct control from Earth. The rovers are operated by a direct control loop, involving the mission control center. In order to direct the rovers safely, a continuous video link with the Earth is necessary to assess its immediate surroundings. Two forward pointing navigational cameras

Among these central examinations come the ones that are performed in the transition from elementary education to secondary education first (Karakaya, 2012. In the transition from elementary education to sec¬ondary education, the results of the Level Determination Examination, known as SBS are used. In order to select students and place them in second¬ary schools, the Level Determination Examination (LDE has been performed for the 6th, 7th, and 8th grades since the academic year 2007–2008 (MEB, 2010a. The Level Determination Examination includes five sub-tests, which are Turkish, mathematics, science and technology, social sciences, and foreign languages (MEB, 2010b. After the elementary curriculum has been renewed in 2005-2006 academic year, alternative measurement and assessment approaches are being used in the classrooms such as project work, classroom involvement, performance work, portfolio, etc. (Atılgan, Kan & Doğan, 2011. Amongst these, project work, classroom involvement, performance work, and formal examinations at school are being used for the transition from elementary education to sec¬ondary education as well as the result of the Level Determination Examination (MEB, 2010a. When the related literature is viewed, it is seen that there are many studies on the effects of the LDE (Sevindik, 2009; Üzkurt & Koçakoğlu, 2009; Anıl et al., 2010; Güler, 2010; Erdoğan, Giorgietti & Çifçili, 2010; Kelecioğlu, Atalay & Öztürk, 2010; Kurt, 2010; Yılmaz, 2010; Anıl & Güzeller, 2011; Bal, 2011; Şahin, 2011; Güzeller, 2012; Karakaya, 2012; Karakaya & Kutlu, 2012.

    The Liquid Phase Methanol (LPMEOW) Demonstration Project at Kingsport Tennessee, is a $213.7 million cooperative agreement between the U.S. Department of Energy (DOE) and Air Products Liquid Phase Conversion Company, L.P. (the Partnership) to produce methanol from coal-derived synthesis gas (syngas). Air Products and Chemicals, Inc. (Air Products) and Eastman Chemical Company (Eastman) formed the Partnership to execute the Demonstration Project. The LPMEOW Process Demonstration Unit was built at a site located at the Eastman complex in Kingsport. During this quarter, initial planning and procurement work began on the seven project sites which have been accepted for participation in the off-site, methanol product-use test plan. Two of the projects have begun pre-testing of equipment and three other projects have commenced with equipment procurement, Methanol produced from carbon monoxide (CO)- rich syngas at the Alternative Fuels Development Unit (AFDU) in LaPorte, TX has been shipped to four of the project sites in anticipation of the start of testing during the first quarter of calendar year 1998. Catalyst activity, as defined by the ratio of the rate constant at any point in time to the rate constant for a freshly reduced catalyst (as determined in the laboratory autoclave), continued to decline more rapidly than expected. In response to concentrations of arsenic and sulfbr detected on catalyst samples from the LPMEOW Reactor, Eastman replaced both the arsine- and sulfiwremoval material in the Eastman guard bed which treats the primary syngas feed stream (&danced Gas) prior to its introduction into both the Eastman fixed-bed methanol plant and the LPMEOWM Demonstration Unit.

    Tagliapietre (Venecija, 1680. – 1747.. U Dalmaciji se relativno skroman opus dosada uočenih Callalovih sastoji od dva mramorna anđela postavljena uz glavni oltar u župnoj crkvi u Vodicama te četiri putta svirača smještena sa strane glavnog oltara, kao i onih na bočnom oltaru u župnoj crkvi u Sutivanu na otoku Braču. No, Callalovu ruku moguće je prepoznati i u jednoj skulpturi iz pozamašnog kiparskog programa na oltaru Presvetog Sakramenta u zadarskoj katedrali. Arhitekturu je 1719. izradio Antonio Viviani dok je bogatu kiparsku dekoraciju najvećim dijelom isklesao Francesco Cabianca (Venecija, 1666. - 1737.. U središnjoj niši oltara smješten je manji mramorni kip Žalosne Bogorodice s mrtvim Kristom u krilu. Mramorna zadarska Pietà teško se uklapa u katalog Francesca Cabiance, pogotovo ako se ima u vidu njegov kip istoimene tematike postavljen oko 1714. nad vrata u klaustru venecijanske crkve I Frari. Cabiancina venecijanska Pietà posjeduje oštrinu poteza dlijeta, određenu grubost izvedbe i robustnost tijela te drugačiju fizionomiju i draperiju od zadarskog djela. No, zadarska se Pietà može uključiti u katalog kipara Paola Callala. Pažljivo modelirani lik žalosne Majke te meko oblikovanu draperiju koja se oko stopala radijalno širi prema van možemo usporediti s kipovima Vjere i Nade na oltaru Sakramenta katedrale u Udine, nastalom nakon 1720. godine. Paralele u modeliranju Kristova tijela, a posebno lica suzdržane mimike, nalazimo na kipu Uskrslog na tabernakulu već spominjanog udineškog oltara, kao i u istovjetnom kipu na tabernakulu oltara župne crkve u Clauzettu, što ga također pripisujem Callalu, ali i na ranijim monumentalnijim primjerima, poput Krista s oltara Preobraženja nastalom 1708. za župnu crkvu u Labinu. Callalov spomenik ninskom biskupu Francescu Grassiju u Chioggi važan je pokazatelj razvoja osobnog stila majstora. Njegov se izričaj tako transformira iz ovog „mladenačkog djela“ punog siline i robusnosti u lirsku

    Full Text Available U članku se razmatra postupak rešavanja problema višeatributnog odlučivanja na jednom nivou kriterijuma i prezentuje metod zasnovan na elementima kompromisnog odlučivanja, Lp metrici i TOPSIS metodu. Daju se preporuke za formiranje početne matrice odlučivanja i transformaciju raznorodnih kriterijumskih vrednosti. Kompromisna rešenja dobijaju se na osnovu vrednosti funkcija Lp metrike i njihovih kombinacija sa koeficijentima − funkcijama relativne verodostojnosti zavisnim od dimenzija problema. Dobijena rešenja zavisna su od parametra p u Lp metrici koji je balansirajući faktor između rešenja sa najvećom ukupnom koristi i rešenja sa minimaks odstupanjima kriterijumskih vrednosti od ideala i antiideala. Ako se zahteva jedinstveno rešenje, ono se dobija objedinjavanjem svih funkcija Lp metrike i primenom vektora sličnosti varijanata idealu, kojim je obuhvaćen i uticaj antiideala. Prikazan je i postupak dobijanja kompromisnih rešenja na osnovu vrednosti elemenata parcijalnih vektora sličnosti idealu i uticaj subjektivno određenog antiideala na rešenja. Primena metoda prikazana je numeričkim primerom. / A method for solving multiple-attribute decision-making problems at one criterion level is discussed, followed by a presentation of a method based on compromise programming elements, Lp metrics and the TOPSIS method. Suggestions for forming the initial decisionmaking matrix have been given as well as for the transformation of multiple criteria values. Compromise solutions are obtained based on the values of Lp metrics functions and their combinations with coefficients – functions of relative credibility depending on solution dimensions. The obtained solutions depend on the parameter p in Lp metrics, parameter p being a balancing factor between the solution with the highest total utility and the solution with minimax deviations of criteria values from the ideal and negative-ideal solutions. If a unique solution is required, it

    zbornika jest i tema vlasništva pojedinog primjerka stare knjige. Upravo tu temu obradio je D. Shaw pod naslovom Tko je bio vlasnik ove knjige? Proučavanje porijekla knjiga u europskim razmjerima. Autor naglašava važnost katalogizacije na temelju pojedinog primjerka jer se jedino tako u kataložnom zapisu mogu zabilježiti sve karakteristike i posebnosti pojedinog primjerka građe. Upravo takav postupak opisa potaknuo je razvoj područja kojim se bavi autor u svome radu - proučavanja porijekla knjige. Važnost proučavanja prethodnih vlasnika jasno se vidi u mogućnosti okupljanja raspršenih knjižnica i privatnih zbirki koje svoju „pripadnost“ određenoj zbirci ponekad mogu dokazati jedino obilježjima vlasnika ili knjižnice kojoj su nekoć pripadali. Osim vlastoručnih potpisa vlasnika i pečata knjižnice, dokazi o prijašnjim vlasnicima mogu se istražiti i uz pomoć signatura, ex librisa, pečata na uvezima itd. Veliku pomoć u toj vrsti istraživanja pruža i Konzorcij europskih knjižnica (CERL koji nudi mrežnu bazu podataka o porijeklu knjiga. Posljednji rad u ovoj cjelini izradila je doktorska studentica M. Tomić pod naslovom Podaci o povijesti primjerka u hrvatskim katalozima stare i rijetke građe. Autorica je prikupila dostupne (tiskane kataloge te je kroz te kataloge i kataložne zapise starih i rijetkih knjiga u online katalozima istražila koliko se bilježe podaci o porijeklu primjerka. U radu su prikazani rezultati spomenutog istraživanja s posebnim osvrtom na podatke o povijesti primjerka ukoliko su (i ako su uopće uključeni u tiskane kataloge stare i rijetke građe u hrvatskim knjižnicama te u online katalozima hrvatskih knjižnica. Dodana vrijednost ovoga rada jest i bibliografija kataloga inkunabula, kataloga knjiga i rukopisa koji se nalaze u muzejskim knjižnicama i crkvenim ustanovama te kataloga izložbi starih i rijetkih knjiga. Neki od izvora koji su istraženi nisu ranije uključivani u postojeće bibliografije stare gra
